In case it's of interest the JBidWatcher ebay sniping program[1] just 
arrived in the Debian unstable repository. I wouldn't buy on ebay any 
other way! 
Incidentally there's a very moving account on Morgan's website[2] 
about what happened when someone ripped off his (open source) code 
and started selling it on ebay. Grrrr.
ATB, Peter
